Abstract
A gearbox for vehicles, comprising a split gearbox (C), a main gearbox (A) and a range gearbox (B), which is shiftable into a low range gear, a high range gear and a reverse gear; the range gearbox (B) comprising a planetary gear () with a ring gear wheel (), a sun gear wheel () and a planet carrier (), on which at least one planet gear wheel () is rotatable mounted, which ring gear wheel () and sun gear wheel () engage with the at least one planet gear wheel (); a gearbox housing () surrounding the planetary gear (); a first axially movable coupling sleeve () arranged to engage the planet carrier () with the gearbox housing (); and a second axially movable coupling sleeve () arranged to engage the ring gear wheel () with an output shaft () for achieving the reverse gear in the gearbox (). The split gearbox (C) and the main gearbox (A) are together arranged to have a combined largest gear ratio which is larger than the gear ratio in the planetary gear () in the range gearbox (B) when the planetary gear () is shifted into the reverse gear.
